  • Patent number: 7954394
    Abstract: A parking switching valve includes a spool that is movable to a first position and to a second position. The parking switching valve also has an oil chamber that generates a biasing force from a difference in the pressure receiving area between the land portions of the spool. The oil chamber has a second input port to which a line pressure is input while the spool is in the second position. Because the line pressure is input to the second input port, a biasing force is generated so that the spool is held in the second position against a spring. As a result, a parking device is held in a parking release state.

  • Patent number: 7835843
    Abstract: An ECU executes a program that includes a step of determining whether an output shaft rotation speed NOUT is equal to or greater than a reference rotation speed at which determining regions with all of the gear speeds in a stepped automatic transmission do not overlap, a step of determining that there is an abnormality in the gear speed by dividing the turbine rotation speed NT by the output shaft rotation speed NOUT if the output shaft rotation speed NOUT is not equal to or greater than that reference rotation speed, and a step of determining that there is an abnormality in the gear speed by subtracting a value, which is obtained by multiplying the output shaft rotation speed NOUT by the gear ratio, from the turbine rotation speed NT if the output shaft rotation speed NOUT is equal to or greater than that reference rotation speed.

  • Patent number: 7699748
    Abstract: An ECU executes a program that includes the steps of setting a line pressure to a line pressure (1) that is appropriate for improving fuel efficiency, if an automatic transmission is not shifting, and a deceleration slip control for a lock-up clutch is not being executed; setting the line pressure to a line pressure (2) that is equal to or lower than a line pressure (3) that is appropriate when the automatic transmission is shifting, if it is determined that the automatic transmission is not shifting, and the deceleration slip control is being executed; and setting the line pressure to the line pressure (3), if it is determined that the automatic transmission is shifting. The line pressure (1) is lower than the line pressure (2). The line pressure (2) is equal to or lower than the line pressure (3).

  • Patent number: 7643924
    Abstract: An ECU executes a program that includes the steps of setting an abnormality flag when a hydraulic pressure switch is on even though a lock-up clutch is in a lock-up OFF state, forcing an SLU off when the lock-up clutch is on and the abnormality flag is on, determining that there is an SLU failure when the lock-up clutch is still in a lock-up ON state after a predetermined period of time has passed, and determining that there is a hydraulic pressure switch failure when the lock-up clutch is not in the lock-up ON state after the predetermined period of time has passed.

  • Publication number: 20090005957
    Abstract: A control system includes a nonvolatile memory of an electronic controller, which stores information regarding operation characteristics of a hydraulic-pressure control valve that serves as an actuator in advance, and an electronic control unit that controls an operation of the hydraulic-pressure control valve based on the information. The electronic control unit is formed separately from the hydraulic-pressure control valve. The electronic controller is formed integrally with the hydraulic-pressure control valve. The control system and the actuator simplify a work for replacing the electronic control unit or the actuator.
